Changed: Set android:process to ${TERMUX_PACKAGE_NAME} for app to run in com.termux process

[twaik]

Running in the main com.termux process instead of a separate one lets the app share its cpuset, so it can be placed in top-app instead of foreground while active, which may improve performance.

While this may work for fixing priority, I dont know how this will affect the termux-float code in this repo and in termux-shared, like if Context.getApplicationContext().getPackageName() gets changed to com.termux, then com.termux.window checks and files won't be used, also not sure how stable this is across Android versions, and any other effects, it would require testing. Also better to fix the priority issue in termux-app itself with the overlay instead of requiring users to install a plugin, regardless of this fix is temporary.
